That party may be: - a person. - a mobile Station through miscellaneous Common Carrier attendant. - a Station, department, or office through a PBX attendant. After the called Station has been reached, if the calling party requests or agrees to speak to a party other than the party initially specified, the call is still classified as Person-to-Person. The calling party is responsible for identifying the party at the called Station. Person-to-Person also applies when the call originator requests an operator to make arrangements with a called party to establish a call at a specified time.

21 Original Sheet General Regulations (Continued) 2.7 Rate Determination (Continued) Timing of Messages Chargeable time includes the initial period plus the additional period, if any, and is determined as follows: A. On all calls, other than person-to-person, chargeable time begins when connection is established between the calling Station and the called Station, PBX, or a mobile radio system for Public Land Mobile Service. B. On Person-to-Person messages, chargeable time begins when connection is established between the calling person and a specified person, Station, department, office or an agreed-upon alternate. C. Chargeable time ends when the calling Station "hangs up". If the called Station "hangs up" but the calling Station does not, chargeable time ends when connection is released either by automatic time equipment in the telecommunications network or by the operator. D. When Exchange telephone service used for IMTS is directly connected (i.e., not connected through a Multiline Terminating System) at a Customer's Premises to a Communications System, chargeable time for all classes of service begins when a call from the telecommunications network terminates in or passes through the first Multiline Terminating System or terminal equipment on that Communications System. It is the Customer's responsibility to furnish appropriate answer supervision to the point of connection with the Exchange telephone service so that chargeable time may begin Determining the Applicable Rate in Effect For all calls, the rate in effect at the calling Station at the time the connection is established applies to the entire call.

22 Original Sheet General Regulations (Continued) 2.8 Credit Allowances for Interruptions Application A credit allowance is applicable to that portion of a call which is interrupted due to poor transmission (e.g., noisy circuit condition), one-way transmission (one party is unable to hear the other), or involuntary disconnection (cut-off) of the call caused by components of IMTS. A Customer may also be granted credit for reaching a wrong number. To receive the proper credit, the Customer must notify the Company operator or Telephone Company office and furnish the called number, the trouble experienced (e.g., cut-off, noisy circuit, reached wrong number, etc.), the class of call, and the approximate time the call was placed. At the Customer's option, when the Telephone Company operator is notified, the operator will attempt to re-establish the call. IMTS charges will apply to the re-established call. A. Interruptions to Established Calls When a call billed under this product guide is interrupted due to cut-off, one-way transmission, or poor transmission conditions, the Customer will receive credit equivalent to one minute (i.e., the last minute of the call). B. Wrong Numbers When a wrong number is reached, a credit equivalent of one minute (i.e., the last minute) for the call will be granted if the Customer reports the situation promptly to the Telephone Company operator or a Telephone Company office. C. When Credit Allowances Do Not Apply Credit allowances for an IMTS call do not apply for: - interruptions not reported to the Telephone Company, - interruptions that are due to the failure of power, equipment or systems not provided by the Telephone Company, or - interruptions caused by the failure of other services provided by the Telephone Company which are connected to IMTS Use of Another Means of Communication If the Customer elects to use another means of communication during the period of interruption, the Customer must pay the charges for the alternative service used.

Collect Calls are permissible between all Stations except that the Collect Call option is not available for calls to a public or semi-public coin Station. 3.3 Rate and Charge Application Mileage Determination Rates for service points in the LATA are based on the airline mileages between rate centers as determined by information provided in Section 5 following. Rate centers to which this product guide applies for the provision of IMTS are listed in Section 4. following. Rates applicable for mileages obtained are as provided in Section 3.4 following. A. Where One Station Involves a Zoned City - Calculate the airline mileage between the rate center of the specific city zone and the rate center of the distant Station. If the mileage determined is forty (40) miles or less, this is the correct mileage for rate determination. If the mileage determined is forty-one (41) miles or greater, recalculate the mileage using the rate center of the distant Station and the master rate center of the zoned city (in lieu of the rate center of the specific city zone). This mileage, with a minimum of 41 miles applicable, is the correct mileage for rate determination. B. Where Both Stations Involved Zoned Cities - Calculate the airline mileage using the rate centers of the specific city zones involved in each city. If the calculated mileage is 40 miles or less, this is the correct mileage for rate determination. If the calculated mileage is 41 miles or greater, recalculate the mileage using the master rate centers of the cities (in lieu of the rate centers of the specific city zones involved). This mileage, with a minimum of 41 miles applicable, is the correct mileage for rate determination.

30 Original Sheet Mileage Measurement 5.1 Mileage Determination A. Rates for service between points in the LATA, Market Area or Corridor, as applicable, are based on the airline mileage between the rate centers involved. B. In general, each point in the LATA, Market Area or Corridor is designated as a rate center except that certain small towns or communities are assigned adjacent rate centers with which they are closely associated for communication purposes or by community of interest and in a few of the largest cities there are several rate centers further identified as city zones. 1. Where a Point is Divided into City Zones The rate airline mileage measured between the rate center of the city zone and the rate center of the other point, except that when such mileage exceeds 40 miles, the rate airline mileage is measured between the rate center of the master zone and the rate center of the other point with a minimum of 41 miles being applicable. 2. Where Both Points are Divided into City Zones The rate airline mileage is measured between the rate centers of the city zones, except that when such mileage exceeds 40 miles, the rate mileage distance is measured between the rate centers of the master zone with a minimum of 41 miles being applicable. C. The rate centers set forth in Section 6 following are arranged alphabetically by state for each LATA, Market Area and Corridor set forth in this Product Guide. D. The columns headed V and H contain the vertical and horizontal coordinates for each rate center. E. For the purpose of determining airline mileages, vertical and horizontal grid lines have been established across the states. The spacing between adjacent vertical grid lines and between horizontal grid lines represents a distance of one coordinate unit. This unit is the square root of 0.1, expressed in statute miles. A vertical (V) and a horizontal (H) coordinate is computed for each rate center from its latitude and longitude location by use of appropriate map-projection equations. A pair of V-H coordinates locates a rate center, for determining airline mileages, at a particular intersection of an established vertical grid line with an established horizontal grid line. The distance between any two rate centers is the airline mileage computed between their respective coordinate intersections as explained following.

31 Original Sheet Mileage Measurement (Continued) 5.1 Mileage Determination (Continued) F. To determine the rate distance between any two rate centers proceed as follows: 1. Obtain the V and H coordinates for each rate center. 2. Obtain the difference between the V coordinates of the two rate centers. Obtain the difference between the H coordinates. The difference is always obtained by subtracting the smaller coordinate from the larger coordinate. 3. Divide each of the differences obtained in (b) preceding by three, rounding each quotient to the nearer integer. 4. Square these two integers and add the two squares. If the sum of the squares is greater than 1777, divide the integers obtained in d., preceding by three and repeat this step 4. Repeat this process until the sum of the squares obtained in 4. is less than The number of successive divisions by three in steps 3. and 4., preceding determines the value of N. Multiply the final sum of the two squares obtained in step 4., preceding by the multiplier specified in the following table for this value of N preceding: Minimum N Multiplier Rate Mileage

32 Original Sheet Mileage Measurement (Continued) 5.1 Mileage Determination (Continued) F. To determine the rate distance between any two rate centers proceed as follows: (Continued) 6. Obtain square root of the product in 5. preceding and, with any resulting fraction, round up to next higher integer. This is the message rate mileage except that when the mileage so obtained is less than the minimum rate mileage shown in E. preceding, the minimum rate mileage corresponding to the N value is applicable. Example: Step 1: Determine the message rate distance between Wilmington DE and Philadelphia (Zone 1) PA. Rate Center Location V H Wilmington Philadelphia Differences: V = 75 H = 27 Step 2: Divide each difference determined in Step 1 by three (3) and round to the nearer integer. V 75 / 3 = 25 H 27 / 3 = 9 Step 3: Square the integers calculated in Step 2 and add the resulting sums. V 25 x 25 = 625 H 9 x 9 = _81 Sum of squared integers 706 Step 4: Multiply the sum of the squared integers by factor 0.9 (corresponding to N = 1). 706 x 0.9 = Step 5: The mileage applicable between the rate centers is equal to the square root of the sum calculated in Step 4 rounded up to the next whole mile. The Square root of = miles which rounds up to 26 miles.
